Introduction

The 74ALVCH16501DGG is part of a series of logic devices from ON Semiconductor. It is a 16-bit Universal Bus/Interface Logic device, designed to provide multiple functions and reduced system power consumption through the utilization of advanced BiCMOS technology. This device consists of an advanced transmit and receive port for communication, with an integrated receiver and transmitter interface. The device also provides two interrupt sources to enable efficient system software control, two clock outputs to maximize system performance, and a Time-Out programmable logic input to initiate a controlled shutdown of the device.

Application Fields

The 74ALVCH16501DGG is designed to support multiple applications, with an emphasis on applications requiring reliable on-chip communication. The device is compatible with multiple communication protocols, and can be used for communication across multiple buses, such as CAN, CAN FD, and Ethernet. Additionally, this device is widely used to enable communication for distributed systems, where multiple devices need to communicate with each other efficiently. Examples of these systems include motor control, factory automation, and communication between multiple systems for maximum system performance.

Working Principle

The 74ALVCH16501DGG works with a Time-Out feature, which enables reliable on-chip communication. This feature sets a specific period of time in which the device should gain control of the bus, complete its communication, and free up the bus for use by other devices. The Time-Out feature works by setting a timer to the maximum number of cycles allowed to complete the communication. If the communication is not completed within that limit, the device stops communicating and releases control of the bus.The device is compatible with multiple communication protocols, including CAN, CAN FD, and Ethernet. These protocols require the device to be properly configured to properly follow the protocol. The device uses memory initialization registers that control the selection of communication protocols, data format, and other configuration activities. Additionally, the device has selectable CRF0, RF1, and RF2 registers which allow for further customization of the communication protocol selections.

Conclusion

The 74ALVCH16501DGG is a 16-bit Universal Bus/Interface Logic device, designed to provide reliable on-chip communication with multiple protocols, reduced system power consumption, two interrupt sources for efficient system software control, and two clock outputs for maximizing system performance. The device utilizes a Time-Out feature for reliable communication, as well as memory initialization registers to control communication protocol selections and improve customization. Overall, the 74ALVCH16501DGG is an efficient and reliable solution for applications requiring efficient communication.
